This invention relates broadly toimproyements in electrical apparatusand more specifically to improvements insockets'for eled tron tubes. I

An object of this invention is to provide.

an electron tube socket from which the electron tube may be readilyreleased for removal or replacement. a

1 Another object of this invention is to provide an electron tube socketin which eflicient' heat radiation isobtained.

A further object of this invention is to provide a compact liquid cooledsocket for liquid cooledelectron tubes which efliciently re.

moves the heat developed in the. electron tube.

Other objects and features of this invention will be apparentto'anyoneskilled in the art from the following specification and claims.

According to this invention the depending anode of an electron tube maybe removably clamped in a compact and unitary cooling liquid structure.Inlet and outlet ports are provided at the bottom of the structurethereby eliminating connections heretofore employed and which protrudefrom the sides, this providing a more compact unit. Clamping members areprovided at the mouth of the structure for engaging a rim surroundingthe anode of the electron discharge device. These clamping members arereadily slipped into engagement with the rim and provide means wherebythe electron discharge deviceis easily replaced. Adjusting screws areprovided on the clamping members whereby the pressure exerted by saidclamping members against the rim surrounding the anode may be varied.The inlet port is furthermore provided with a curved passagewayextending into the interior of the structure for imparting rotary motionto the water jet issuing from the inlet port. More effective cooling ofthe anode of the electron discharge device is obtained in this manner.

In the drawings, Figure 1, partly in crosssection, illustrates oneembodiment of this invention; Fig. 2 shows a cross-section along theline 22 of Fig. 1; Fig. 3 shows a vertical the depending anode of theelectron dissectional View along'the line 33 of Fig. 4 of the base oftheelectron tube socket; and Fig.4 shows a cross-section of the socketstructure along the line 1" 1 of Fig. l.

Likereference characters are used to designate like parts throughout allthe figures of'the drawings. Referring to Fig. 1 of the drawings indetail, 1- designates a liquid; cooled'electron discharge tube; 2designates 6O charge tube. A rim or flange 3 is provided on theanode'for' engagement with an inwardly extending flange 7 of the member7 A tubular member 10 adapted to' surround the anode electrode of theelectron discharge device is fittedover the portion '11 of the plugmember 13. A tubular member 9 adapted to enclose the tubular member 10is fitted over' the portion 12' of the member 13. The mem ber 7 isadapted to engage the tubular member 9 at the end opposite to thatengaging the member13. J

The electron discharge device 1 is placed with its anode 2 within thetubular member 10 and is supported upon'the flange 7"by' the rim 3.Adjustable clamp members 4 in the form of rocker levers are supported byrod shaped pivot members 6 upon-the"member 7 Adjustable screw members 5are screw threaded through the member 4. Poretions of the clamp members1 are adapted to engage therim 3 to holdthe electron discharge device inposition with respect to the tubular members 9 andr10. Screw members 5bear against portions of the member 7 and thereby provide'means wherebythe rigidity with which the electron discharge tube is held within thetubular membersmay bevaried.

An electrostatic shield 8 is provided adj acent'to the anode and flaresout along-the tube. This shield is made preferably, of relatively thincopper or brass spun into shape and secured by screws or other means' tothe member 7. The shield may be made integral with I the member? ifdesired. -95

The plug. member 13 is provided with'the outlet and inlet ports 15 and"18, respectively. Pipe fittings l6 andi17 for making hose connectionsto the outlet and inlet ports 15 and 18 respectively are also providedin the plug member 13. The inlet passage through the member 13 ishelical in order to impart rotary motion to the cooling liquid enteringthe socket structure and facilitate cooling of the anode 2. The pipefittings 16 and 17 are provided at the bottom of the socket structure inorder to reduce the cross-sectional area of the socket and render itless bulky. This type of construction lends itself more readily todesign requirements and is also simpler in man ufacture.

In Fig. 2 of the drawings is shown a crosssectional view illustratingthe manner 'in which the electron discharge device is se-1 cured in thesocket structure. The clamping members I are slidable longitudinally ofthe pivot member 6 when the screws 5 are loosened. To remove theelectron discharge tube it is only necessary to loosen the screws 5 andslide the clamping members 4 on the pivot members 6 back adjacent to thesupport 19 out of engagement with the flange 3. The position of theclamping members i when the tube 1 is to be removed from the socket isshown in dotted outline in Fig. 2.

In Figs. 3 and 4 are illustrated the helical shaped passage of theliquid cooling medium inlet. The cooling medium passes up through thepassage 18 into the space within the tubular member 10. The-coolingmedium then comes into contact with the anode of the electron dischargedevice and passes into the jacket formed between the tubular members 9and 10 and out through the outlet port 15 as indicated by the arrows.

1 Although I have described this invention with respect to a particularconstruction it is, of course, understood that various modifications maybe made in the detailed constructi on thereof without departing from thescope of this invention as defined by the appended claims.

What I claim as new and desire to secure by Letters Patent of the UnitedStates is as follows 1. An apparatus of the class described, includingan electron tube having an external anode and a source of electronsthere for, a pair of concentrically related jackets arranged to receivesaid anode, means for circulating a cooling fluid around said anode andbetween said ackets, means adjacent the top of one of said jackets forsecuring said anode in position, said means comprising a pair ofball-crank levers, a supporting pivot thermionic tube having an externalanode and a source of electrons therefor and comprising a socketstructure arranged to receive said anode, a laterally extending flangeon said anode, a head carried by said socket structure, a pair of rodmembers-carried by said head, extending parallel to each other onopposite sides of and in a plane perpendicular to the axis of saidsocket structure, rockable levers mounted on said rodmembers andadjustable laterally on said rod members with respectto said head fromdiametrically opposite positions with respect to said flange on saidanode to positions beyond said flange for securing or releasing saidanode from said socket. l

3. A device of the class described including an electron tube having anexternal anode and a source of electrons cooperating therewith, a socketstructure arranged to receive said anode, a laterally extending flangeon said anode, a head carried by said socket structure, said socketstructure comprising two fluid conducting members, a pair of parallelpivot rods carried by said head on opposite sides thereof, said rodsbeing substantially perpendicular to the axis of said socket structure,rockable clamps carried respectively by said rods and slidable laterallyalong said rods and adjustable screws carried by each of said clamps andadapted when adjusted to bear against saidhead and lock said clamps intoengagement with the flange of said anode to retain said anode in saidsocket structure.
